Application liled March 22, 1886.

To an whom, it may concern:

v Be .it known that I, Moses G. HUBBARD, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in A utomatia Twine- Unwinders, of which the following is a full and exact description, reference being had to the :in an application filed by me January 28, 1886,

i No. 190,061, and allowed.

lVIy invention consists, first, in the combiaccompanying drawings, making part of this specification. '1 o My invention relates to that class of devices for unwinding twine similar to that described nation of a rim having a hub connected thereto by means of spokes or arms, a shaft, with or upon which said hub is adapted to revolve, and a spool shaft and clamp, as-hereinafter described.

i It further consists in the combination, 'with aspool having its ends made in disk form, of

a rimjadapted to revolve around one end 01' the spool, whereby all the twine can be easily drawn therefrom.

Q .It further consists in the combination of a spool shaft and clamp, a rim secured to said gshaftand capable of revolving around the the spool'suppo'rtor base, of the arch or bail [secured thereto, and having the guiding-eye arranged therein. I

- It further consists in the combination, with the spool-and rim, of a stop for checking the twine when the force or pull ceases thereon.

I ,It further consists in the combination, with the-revolving rim and hub connected together 14,

by means of the arching spokes or arms formng-openlngs between said hub and rim, of

uponits'upper endand projecting above the spool, whereby the shaft can bereadily de tached from the base or support, all said parts being constructed and operating substantially 'in the manner, and for the purpose set forth.

My invention is designed for use by'merchants, to stand on their counters, and others, who use twlne hurriedly or at intervals, and

is adapted to avoid the taugling and other Serial No. 106,149. x 1110(101.) i

troubles which occurin unwinding the balls in which twine is now-furnished and used, and to check the unwinding of the twine'immediately upon the termination of the force or pull by which it is unwound.

1n the accompanying drawings, Figure 1 is a perspective view of the device complete. Fig. 2 is a longitudinal section of the same. Fig. 3 isa plan or,top view of I a modification in the manner of connecting the rim and hub. Fig. 4 is abottom view of the device, showing one-manner of holding the spool shaft and clamp connected with thebase; and Fig. 5

shows a modification of such device. Fig. 6 is a horizontal cross section of the spool O.

The base K is made of any suitable cast material that will polish and finish up neatly, and it is hollowed out on the under side, as shown, to secure lightness and afford room under iti'or the boss or hub a, in which a screw-thread is out to receive the screw-thread a on the lower end of the spool shaft and clamp B, as shown in Fig. 5,'or the boss or hub is made in cam form, and with which a lug, a", on the lowerend of the spool shaft and clamp engages,as shown in Fig. 2, and by means of either of which constructions a heavy spool of twine may be firmly clamped to the base, and thereby adapt the device for use in any desired position, as well as to stand on a'mer chants counter.

On the upper end of clamp, 13 are formed three slanting projections, b, to fit into and rest upon the upper the spool shaft and end ot'the tubular portion of the spool 0, hereinafter referred to, and hold the same firmly in position. This clamp maybe made hollow or tubular to permit the rim-shaft D to pass through it, and upon the upper end of this shaft is attached a large rounded. rim, E, by

the intermediate arms, F, and hub G, and in such manner as to revolve freely with or upon the same. i This large rounded rim E is either cast in onepiece with thearins and hub, as

shown in Fig. 3, or may be formed as shown in Figs. 1 and-'2, in'which. figures it is shown a s un over. out of sheet metal, by suitable -machinery for this purpose, and this spun rim is attached to arms or spokes F, connect-ed with the hub, said spokes or arms being so formed at theiri uner ends as to permit a wrench I or the fingers to be applied to a flange or ear, B, formed upon the upper end of the spool shaft and clamp for engaging or disengaging the same from the base. I To the base A is attached an arch or bail, H, which extends over the rim, as shown, and which arch or bail serves the double purpose of a support for the centrally-located guidingeye, K, and also as a convenient handle or bail for handling or carrying the spool. This arch, when formed as shown, also adds to the neat appearance of the whole device. in which ornamentation ismuch desired. On one or both sides of the arch is attached a stop, L, to stop the twine, preventing it from spinning ofi by the continued revolution after the force or pull used to draw oil the twine ceases. This stop may be rigid and extend from the side of the arch near enough to the rim to catch and stop the twine, to preventit from spinning off;

orit may be in the form of a light spring touch ing or approximating the rim, or it maybe made slightly stiffer, and act as a light yielding brake uponthe rim. v To the device, as above described, a spool is attached, constructed in the following manner: The spool-hub is made of thin sheet metal, having end disks also formed of thin sheet metal. In the drawings the central hub,O,is shown as being formed, as before stated, from thin sheet metal of suflicient diameter to receive the shaft or clamp,and at each end of said hub is formed a small head or shoulder, G, and upon the ends thus formed are mounted the thin sheet-metal'disks C, perforated centrally, to fit closely around the central hub, the-hub being of sufficient length to project slightly beyond the outer face of the disk at each end. After the disks have been thus applied to the hub'the projecting edges are bent or turned over, as shown at 0, upon the outer facesrof the disks. This construction and form of spool adapts the same to hold a large amount of twine'within a convenient space, and by this construction and form of spool, in connection with the large rounded rim,the twine is adapted to be drawn freely from the spool at almost any angle, and this large roundedrim provides especially for the drawing of the twine from a spool of this construction near its up per end,where the twine must be drawn from the spool at quite an acute angle, and as the twine is used intermittently and frequently jerked ofi hurriedly the large rounded revolving rim is indispensable to accomplish it successfully.

The operation of my improved device is as follows: The end of the twine is passed from the spool over the large rounded surface of the rim and up through the centrally-located stationary guiding-eye, and when a sudden jerk or a slight force or pull is exerted upon the twine it will easily and freely slide over the la; ge rounded surface ofthe r1 of the twine around on the rinrrina'c .a rounded enlarged edge, 'This constr the spool shaft and clamp arejcon lengthwise of the twine, the rim and thereby avoid'the necessity 'of thesli direction to unwind the twine fro'm'the and. however stifi or rough? or however many knots i'nt e twine,

not thereby be impeded in' sliding lengthwise over the rim, because the circle'of the rounded surface (or section) of the rim is so mueh largerthan the obstacles on thesn'rfaceof the twine that it will slide lengthwise easily d freely, and, however much momentum y e 1 given to the unwinding 'twine'b'y its revolution, the step will check it instantly uponjthe termination of the endwise'foree or :pullTupon'j the same, and thereby preventit mtflying s or spinning oft fromthe spool when nwoundj; intermittently. t

I have shown in the drawings the) of rim is disclaimed in this case, as the, features-thereof constitute the subjec o case N o. 2u9,326, filed J uly-28, 1886;
